PAP R-comma aim connncrm'e MACHINE.

To all whoinit may concern:

Be it known that I, HORACE DR-UMMOND BLACK, asubject of the King of Great Britain, residing at 56 Tabernacle, street, F insbury, London, England, have invented a new and useful. Paper Cutting and Collecting Machine, of which the following is a specification.

This invention relates a machinefor cutting or dividing into separate books or pads counter check and like book which are a machine the cutting operation of which made with two or more forms 0 a leaf so as to form a strip of books, and for collecting inqiumerical order the books after the cutting operation.

It is found inpractice that books of the above type cannot be cut 'on ordinary paper cutting machines or guillotines without be-' ing damaged, by reason of the fact that the stub or edge of the book, where the leaves are bound together, being of less thickness than the'body of the, same,where the leaves are foldedon each other, cannot be clamped by the platen of thecu'tting machine and is consequently liable to be torn while being cut, particularly as each leaf is perforated where'the difi'erence in thickness occurs.

The object of my invention is to construct will not possess the above defect and at the same time the books will be cut more expeditiously and their numerical sequence be maintained during their delivery from the machine.

According to the invention I provide in 'a' machine a series of pairs of fixed and movable knives pivotedtogether at one end, a series of platens or the like for clamping eachbook strip while being cut, means for feeding the book strips to the knives and means for collecting them after being cut in the same order as that in which they are fed to the knives. i

In a suitable arrangement for carryingout the invention I provide a table mounted on suitable side frames and having a moving fence thereon, either in the form of an -endless band with projections thereon, or

designed to be reciprocated to carry the book .strips between the series of fixed and piv oted knives. The knives are mounted above an opening in' the table and are adjustable across the machine-so that they can be spaced according to the lengths thestrips Specification of Letters Patent.

have to be "divided The fixed orlower- Patented May 21, 1 912.

knives-arearranged horizontally and their upper surfaces are flush with the tableand form a support for the strips when betweenthe knives. The front ends of the upper knives are jointed to a horizontal bar recip rocated vertically in two upper side frames so'that the said knives have imparted to them a scissors-like action. i

A clamping platen is provided in conjunction with each pair of knives to clamp the 'work during the cutting operation, these platens being attached to a second hori- .zontal bar also reciprocated vertically in the upper part of the side frames. U

The book strips are carried between the knives by the moving fence with the stub edge forward to recelve the cutting action of the knives first, and when the out has been completed and the pivoted knives and platens returned to the open posit-ion, the

severed books are guided on to a traveling endless band or the like which carries them towardthe back of the machine where the, books are allowed to fall in an upright position on to a horizontal collecting platform wherethey are moved and maintained in proper sequence by a horizontally recipro- ,cating fence and a vertically reciprocating prong fence cooperating in a known manner.

Toenable the invention to be fully underto the accompanying drawings, in which:-- Figure 1 isa side elevation of' a machine constructed according to my invention.

Fig. 3' is a plan thereof. Fig. 4 is a sec- Fig. 2 is a front elevation of the same, and

tional side elevation of the machine. Fig. 5 is a side elevation of a portion of the feeding mechanism drawn to an enlarged scale, and Fig. 6 is a plan thereof. v

a, a are the side frames of the machine and b is the table connecting thei'ga'said,

frames together and on which the work is initially placed as hereinafter described;

0, (1 indicate each pair of fixed and movable knives. In the drawings two pairs of knives are shown-for cutting a book stri into three books. Each fixed or lower kni e a is carried by a bracket 0 adjustably attached to a recessed portion 1). of the table stood I will describe the same by reference band the movable or upper knife d is carried on abar fdpivoted at one end at d to the bracket 0?,the other end of the bar al being jointed to. an adjustablecollar -e 9n a bar c extending across thesmechineand designed to be reciprocated in guides e in the upper part of the side frames a, a by means of connecting rods 0 actuated by cranks e on a shaft f, the said shaft being rotated from the main shaft 9 through the medium of gear wheels h, h sliaft h and gear wheels if, h.

9 g are fast and loose pulleys on the shaft 9.

i, i are a pair of endless sprocket chains passing around sprocket wheels 77, 1' below the level of the top of the table I) but work ing in parallel slots If, I) therein, the sprocket wheels 6 2' being carried on a shaft i designed to be driven from the gear wheel h through the medium of the gear wheel i shaft 5, sprocket wheel i, sprocket chain i and sprocket wheel 2' The sprocket wheels 7?, 2' revolve on fixed studs i 2' carried by the table I).

j, j are the projections carried by thec-hains i, z and constituting the fence for feeding the book strips between the knives c, (5 one of said strips with the stub end forward beingindicated in position in front of the fence by the dotted lines A in Fig. 4. The position of the book strip between the knives c, d for each cutting operation is determined by stops 7c, 70, and as the strip when in this position would form an obstruction to the continued movement of the projections j, j I provide for turning the said projections back out of the way to enable them to pass the said strip. For this purpose, as shown clearly in Figs. 5 and 6, which illustrate one of the said. fence projections j and its supporting chain, I arrange the said projection on a pivot 7' and I provide it with a boss 7' having a series of notches 7' in its periphery with either of which engages a spring pin 7' so that the said fence will be held by the said pin either in the upright position shown in Fig. 5, or the turned down position shown by the dotted lines also in the said figure. For effecting this turning inrwement the projection 7' is provided on one side with a lug designed to impinge against a stud 70 carried by a bracket 70 adjacent 'to the sprocket wheel i, with the result that the projection 7' is turned from the upright position shown in the full lines into the turned down position shown by the dotted lines. By this constructionrit will therefore be seen that after having moved the strip to the position shown at A Fig. 4-, the projection j will be freed from the said strip. In order that each projection 7' shall be again raised to the upright position in order to again act as a fence for another book strip, a plate Z is provided having a cam surface Z with which a roller Z carried on an arm Z on the proectlou will impinge as the said pro ection is again rising toward the surface of the table.

b is a cross fence and b a side fence,'both being attached to the table ?2 and serving to determine the initial position of the strip to be severed on the table 7), As the fence 7f is in the line of movement of the lug k" onone of the fence projections 7' and would obstruct the latter, it is pivoted at one end to the table 0, 'the lug Z: lifting it slightly in passing.

m, m are the platens for clamping the book stripswhen in the position A the said platens being arranged to clamp the strips against the lower knives c, 0 and being carried by vertical rods m m, adjustably supported by a bar m extending across the machine and working in guides 'm. in the side frames thereof, the said bar being reciprocated vertically by rods m, m having rollers-engaging cam grooves m, m in disks m, m mounted on a shaft it operated from the shaft f through the medium of gear wheels 12 M.

In order to accommodate the'platens to varying thicknesses of book strips, springs 0, 0 are arranged between the said platens and the underside of the cross bar m 7; is the traveling endless band on to which the books or portions of the severed strip are deposited after the cutting operation, the said band passing around rollers 71 ,72 the roller p being rotated from the gear wheel a through the medium of the gear wheel q, shaft 1", bevel-wheels s, s, shaft s and bevel wheels's s, the bevel wheel 8 being mounted on the shaft sf carrying the roller 1).

Instead of allowing the portionsof the severed strip to fall from between the knives directly on to the band p, I prefer employ means for positively transferring them to the said band. These means advantageously comprise a series of airs of supporting plates t, and covering p ates t the supporting plates t being normally flush with the top of the table, as indicated by the dotted lines in Fig. 4, with the covering plates above them sufiicient space being left between the said plates for the book strip to pass into the position A so that after the cutting operation the two series of plates are moved down from the dotted line position to that shown by the full lines,

the severed strips supported on the plates t then sliding from the latter on to the band 77. The requisite oscillatory movement is imparted to the plates tby a rocking shaft u, carrying the said plates, from a cam u on the edge of the disk of one crank 0 rod 'uF and crank arm a on the shaft 11. The

.plates 23 are hinged to the lower ends of upefl'ected from another cam won the edge of the disk of the said crank e through the medium of the rod on, lever w carried upon one end of the shaft w, mounted in bearings 'in the frame sides aand levers w on each end of the said shaft w and links w the lever to being formed integral with one ofthe levers w. The lates t are normally held in an incline position so as to conform more or less to the inclination of 'the plates 25" when the latter are moving 1 down carrying the severed portions of the book strip. As, however, it is necessary that the plates 25 should assume a horisupported upon guide rods 3 and actuated from cam grooves 3 in disks y". through the medium of the rollers links double armed/levers y and links 3 z is the vertical reciprocating prong-fence cooperating w th the fence yflthe severed portions of the book strip falling into the space betweenthe two fences in an upright position and being pressed by the fence toward the fence 2, the latter being at the 'same time lowered out of the way of the said deposited strip and being again moved up into recesses 2 a, in the fence y so that when the latter moves, again forward to form a space for the reception of further severed strips the fence 2 will hold the severed portions of the strip previously referred to against the movable stop fence 2 Thepronged fence 2 is supported at each end, on aslide a which slides are reciprocated in upright guides 2*, 2 by levers 2 actuated by cam grooves z in disks 2.

The operation of the machine is as follows :A strip to be severed is placed in position on the table I) with its back edge resting against the fixed fence b and with one of its ends bearing against the movable side fence I) and assuming the projections j forming the feeding fence have not risen to project above the table, on starting the machine the said projections will come into position above the table top and into contact with the back edge, of the book strip which will be mo"ed into position between the knives against the stops 7c, 70. The platens m and knives d, d will then simultaneously descend to secure the strip, and sever it into the required book lengths which will then be partly supported upon the lower knives c, 0 and plates t, t the saidthe fences y and a.

latter plates t, t' together with plates it, t then descending and depositing the severed portions :Jof the strip upon the band p which will transfer theminto the space between Each severed strip is then in turn moved along the collecting platform 1 and packed-one behind another in their proper sequence between the fence 2 and the movable stop fence 2?. When a suf- 'ficient number of strip portions or books have been collected 011 the platform y the stop'fence a may be removed to allowof the removal of the said books thefencee being returned into position against or in proximity to the pronged fence 2.

Although I have described the machine 7 as designed to, sever the book strips-into three portions, by altering the number of knives, platens and transferring plates and adjusting them to the required distances apart, the strips may be severed into a greater or less number of portions.
